Abstract

Loss reduction apparatus (62, 162) for a fluid transfer system (10) includes a fluid device (20, 40, 50). The fluid device (20, 40, 50) defines a first fluid path along which a greater part of a fluid flows in a first condition, and a second fluid path along which a greater part of the fluid flows in a second condition. The apparatus is arranged so that when a leak occurs at a location (18) in the system, the leak causes a relative reduction in fluid pressure at the location, which moves the device from the first condition to the second condition.
